Abstract
The utility model discloses a straw powder and coal burning double-purpose water-fire tube boiler with a longitudinally configured single drum, which comprises the following components: the longitudinally configured single drum (1), an upper furnace wall (2), a lower furnace wall (3) and a combustion chamber (4). A coal bunker (8) is provided in front of the boiler. A coal outlet of the coal bunker (8) is connected with a chain grate (9) which is provided below the combustion chamber (4). An air blasting chamber (10) is provided below the chain grate (9). The side wall of the combustion chamber (4) is provided with a light fuel inlet (11) which inclines to the front part of the boiler. The straw powder and coal burning double-purpose water-fire tube boiler has an advantage of novel concept, and is reconstructed based on water-fire tube boiler with a longitudinally equipped single drum, which is widely applied. Through reasonably configuring the coal bunker and the light fuel inlet, the straw powder and coal burning double-purpose water-fire tube boiler has double functions of: burning coal, and burning straw powder. Low cost and high technical reliability are obtained. Reuse of the novel energy is realized. Waste is changed into resource.
Description
Technical field
The utility model relates to fire tube boiler, specifically, be the not only flammable stalk powder vertically arranged of a kind of single drum, but also can coal-fired dual-purpose fire tube boiler.
Background technology
The version of boiler is varied, and traditional boiler is many to act as a fuel with coal, and the fume emission behind the coal burning can pollute environment in atmosphere.Along with the continuous enhancing of human environmental consciousness, how People more and more is concerned about novel light fuel such as how effectively utilizing stalk, turns waste into wealth, and reduces the pollution that atmospheric environment is caused simultaneously.
The supply of considering stalk fuel receives seasonal effect bigger, needs a kind of multi-function boiler of can burning straw, again can burning coal of design, with guarantee in the stalk source not enough or lack in, it is idle that equipment is unlikely to.
The utility model content
The purpose of the utility model provides a kind of single drum simple in structure, that floor space is little and vertically arranges combustion stalk powder coal-fired dual-purpose fire tube boiler, can be with stalk or the coal source that acts as a fuel.
For this reason; The technical scheme that the utility model adopted is: the coal-fired dual-purpose fire tube boiler of the combustion stalk powder that a kind of single drum is vertically arranged; Comprise vertical layout single drum (1), go up furnace wall (2), furnace wall (3) and combustion chamber (4) down; Said combustion chamber (4) is positioned at the below of said drum (1), and this combustion chamber (4) fire tube (5) interior with vertically being arranged on said drum (1) communicates, and the left and right sides of said combustion chamber (4) is provided with header tank (6); Said header tank (6) is communicated with said drum (1) through water pipe (7) respectively; Key is: the place ahead of this boiler is provided with coal bunker (8), and the coal outlet of said coal bunker (8) links to each other with the traveling-grate stoker (9) that is arranged on below, combustion chamber (4), is provided with air blast (10) in the below of said traveling-grate stoker (9); Have light Fuel inlet (11) on the sidewall of said combustion chamber (4), said light Fuel inlet (11) tilts to the place ahead of boiler.
This utility model thinking is novel; On the fire tube boiler that single drum of extensive use is vertically arranged, transform; Through coal bunker and light Fuel inlet rationally is set, make it have two kinds of functions of burning coal and stalk concurrently, cost is low, engineering reliability is high; Realize the utilization again of novel energy, turn waste into wealth.
Description of drawings
The structural representation of Fig. 1 the utility model.
The left view of Fig. 2 Fig. 1.
The structural representation of boiler body in Fig. 3 the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
The dual-purpose fire tube boiler that single drum as shown in Figure 1 is vertically arranged is made up of boiler body, last furnace wall 2, following furnace wall 3, combustion chamber 4, coal bunker 8, traveling-grate stoker 9, air blast 10, electrical control cubicles 14, pipeline valve instrument 15, rear pass 16 and economizer 17 etc.
Boiler body as shown in Figure 3; By the single drum 1 of vertical layout, vertically be arranged on fire tube 5 in the drum 1, two header tanks 6 and water pipe 7 etc. and constitute boiler; Body is the left-right symmetric structure; Header tank 6 is communicated with drum 1 through water pipe 7 respectively, water pipe 7 wherein one be that water inlet pipe, another root are outlet pipe.
Can know in conjunction with Fig. 1, Fig. 2, Fig. 3; The right side, bottom that the lower left side of drum 1 is provided with left flue, drum is provided with right flue; Left side flue and right flue are symmetrical set; Constitute the flue 12 that is " eight " font, the front end of flue 12 communicates with fire tube 5 through front smoke box 13, and the rear end of this flue 12 communicates with combustion chamber 4.Combustion chamber 4 is positioned at the below of drum 1, and this combustion chamber 4 communicates with fire tube 5 through flue 12.Header tank 6 is arranged on the left and right sides of combustion chamber 4, and the structure and the arrangement of the dual-purpose fire tube boiler that the above and traditional single drum are vertically arranged are identical.
Difference is: the place ahead of this boiler is provided with coal bunker 8, and the coal outlet of coal bunker 8 links to each other with the traveling-grate stoker 9 that is arranged on 4 belows, combustion chamber, below traveling-grate stoker 9, is provided with air blast 10, and traveling-grate stoker 9 passes through motor-driven; Have light Fuel inlet 11 on the sidewall of combustion chamber 4, light Fuel inlet 11 tilts to the place ahead of boiler.
When needing fire coal, in coal bunker 8, add coal, coal is carried through traveling-grate stoker 9 from left to right, and under the effect of air blast 10, sends into combustion chamber 4.Coal is compact fuel, and its charging needs traveling-grate stoker 9 auxiliary completion; When needing fire coal; Traveling-grate stoker 9 quits work, stalk powder by the light Fuel of boiler body side inlet 11 by after spray into combustion chamber 4 forward, the light Fuel 11 inclined forward settings that enter the mouth; Front portion by last furnace wall 2 keeps off go back to combustion chamber 4, is convenient to stalk powder and fully burns.
The high-temperature flue gas that after 4 burnings of combustion chamber, produces; From the rear portion, combustion chamber upwards the flue through being " splayed " to front smoke box 13; Fold into fire tubes 5 by front smoke box 13 again, take out by air-introduced machine then and draw through back smoke box, rear pass, economizer, after chimney row to atmosphere.Simultaneously, the water in the header tank 6 carries out heat exchange through water pipe 7 inflow drums 1.
